Effects of straw amendment on the bioavailability of selenite in soil and its mechanisms.

Dissolved organic matter (DOM) released by straw returning for decomposition interacts with selenium (Se) in soil, which affects the speciation distribution of Se and its bioavailability. However, the relative mechanisms involved are slightly understood. This study investigated the effects of straw-derived DOM on two levels of exogenous selenite (low-Se and high-Se treatments) in two types of soil with distinct pH.

Electrophoresis-Correlative Ion Mobility Deepens Single-cell Proteomics in Capillary Electrophoresis Mass Spectrometry.

Detection of trace-sensitive signals is a current challenge in single-cell mass spectrometry (MS) proteomics. Separation prior to detection improves the fidelity and depth of proteome identification and quantification. We recently recognized capillary electrophoresis (CE) electrospray ionization (ESI) for ordering peptides into mass-to-charge (m/z)-dependent series, introducing electrophoresis-correlative (Eco) data-independent acquisition.

Single-Nucleus RNA Sequencing Reveals That Gabra6 Neurons in Prefrontal Cortex Promote the Progression of PTSD After Shockwave-Induced TBI.

Shockwave-induced traumatic brain injury (TBI) results in the onset of post-traumatic stress disorder (PTSD), triggered either by the TBI itself or other stressors. However, the interplay and underlying mechanisms of how these factors synergistically induce PTSD remain inadequately elucidated. Here, mice in the TBI (induced by biological shock tube blast injury) and PTSD (induced by single prolonged stress method) groups both displayed symptoms of PTSD behaviors, with the TBI+PTSD (composite model) group exhibiting more severe manifestations.

Therefore, we conducted a meta-analysis to evaluate the efficacy and safety of anti-angiogenic drugs combined with chemotherapy (CT) for platinum-sensitive OC (PSOC) or platinum-resistant OC (PROC).

Methods: A comprehensive literature search was conducted across several databases, including PubMed, Web of Science, Embase, and the Cochrane Library, encompassing all pertinent randomized controlled trials (RCTs) up to 31 May 2024.

The changing treatment landscape of EGFR-mutant non-small-cell lung cancer.

The discovery of the association between EGFR mutations and the efficacy of EGFR tyrosine-kinase inhibitors (TKIs) has revolutionized the treatment paradigm for patients with non-small-cell lung cancer (NSCLC). Currently, third-generation EGFR TKIs, which are often characterized by potent central nervous system penetrance, are the standard-of-care first-line treatment for advanced-stage EGFR-mutant NSCLC. Rational combinations of third-generation EGFR TKIs with anti-angiogenic drugs, chemotherapy, the EGFR-MET bispecific antibody amivantamab or local tumour ablation are being investigated as strategies to delay drug resistance and increase clinical benefit.

Neuronal TCF7L2 in Lateral Habenula Is Involved in Stress-Induced Depression.

Depression is a complex psychiatric disorder that has substantial implications for public health. The lateral habenula (LHb), a vital brain structure involved in mood regulation, and the N-methyl-D-aspartate receptor (NMDAR) within this structure are known to be associated with depressive behaviors. Recent research has identified transcription factor 7-like 2 (TCF7L2) as a crucial transcription factor in the Wnt signaling pathway, influencing diverse neuropsychiatric processes.

Multi-Target Vehicle Tracking Algorithm Based on Improved DeepSORT.

In this paper, we address the issues of insufficient accuracy and frequent identity switching in the multi-target tracking algorithm DeepSORT by proposing two improvement strategies. First, we optimize the appearance feature extraction process by training a lightweight appearance extraction network (OSNet) on a vehicle re-identification dataset. This makes the appearance features better suited for the vehicle tracking model required in our paper.

Ignoring the food route underestimated human health risk from potentially toxic elements in agricultural environments of Ziyang, Shaanxi, China.

Staple food is a crucial exposure route for the human intake of potentially toxic elements (PTEs), but it has been neglected in previous human health risk (HHR) studies. Lack of attention to this issue will lead to an underestimation of HHR caused by PTEs. This study establishes a comprehensive regional identification method for health risk assessment (HRA), namely, soil-maize health risk assessment (SMHRA) and applies it to Ziyang, Shaanxi, which is a typical agricultural county.

Thin Zinc Electrodes Stabilized with Organobromine-Partnered HO-Zn-MeOH Cluster Ions for Practical Zinc-Metal Pouch Cells.

The utilization of thin zinc (Zn) anodes with a high depth of discharge is an effective strategy to increase the energy density of aqueous Zn metal batteries (ZMBs), but challenged by the poor reversibility of Zn electrode due to the serious Zn-consuming side reactions at the Zn||electrolyte interface. Here, we introduce 2-bromomethyl-1,3-dioxolane (BDOL) and methanol (MeOH) as electrolyte additive into aqueous ZnSO electrolyte. In the as-formulated electrolyte, BDOL with a strong electron-withdrawing group (-CHBr) tends to pair with the HO-Zn-MeOH complex, leading to the formation of organobromine-partnered HO-Zn-MeOH cluster ions.
